CA 2573936

A method for optimizing a bioleaching process, at least in respect of heat generation and primary copper sulphide leaching, by actively monitoring and controlling inorganic and organic compounds in a raffinate solution, produced in the process, to levels below that which could be inhibitory to microbial activity of bioleaching strains used in the process.

La présente invention concerne un procédé qui permet d'optimiser un processus de biolixiviation, au moins pour ce qui se rapporte à la génération de chaleur et de lixiviation du sulfure de cuivre de première fusion, par la surveillance et le contrôle actifs de composés inorganiques et organiques présents dans une solution de raffinat, produites dans le processus, à des niveaux inférieurs au niveau qui inhiberait l'activité microbienne des souches de biolixiviation utilisées dans le processus.
